Carolinaia rhois sp. n.
This species seems to be most closely related to Carolinaia
caricis Wilson, and Carolinaia cyperi Ainslie, but there are
characters of structure and c(

olor which will readily separate
the species. The antennae and
and cornicles are dark brown to
black, while in C. caricis they
are dusky yellow. The sixth
antennal segment is about three-
fourths as long as the third and
is considerably less than half as
long as the spur while in C.
caricis the sixth segment is
about half as long as the third
and slightly shorter than the
spur. This species can be sepa-
rated from C. cyperi by the fol-
lowing characters: the sixth an-
tennal segment is as long as or
longer than the fourth while in
C. cyperi the sixth is shorter
than the fourth. The third an-
tennal segment bears six to ten
sensoria which vary greatly in size and which are arranged in
an irregular row along the segment; in C. cyperi the third seg-
ment has five to seven large sensoria which vary little in size
and which are arranged in a more even row.

DESCRIPTION OF ALATE VIVIPAROUS FEMALE
General color very dark green to black. Length of body including the
cauda 1.32 m.m. to 1.55 m.m., width of thorax .638 m.m. to .723 m.m. Head
normal, about twice as wide as long, without prominent antennal tubercles;
eyes rather large, black, with prominent ocular tubercles; head black.
Antennae black slightly shorter than the body, six-segmented. Segment
III about two thirds as long as spur of VI, rather uneven in diameter with
six to ten circular sensoria varying greatly in size and irregularly spaced
along the segment in an uneven row. Segments four, five and six base
about equal in length, each being about three-fourths as long as segment
three. The fourth segment without sensoria, the usual primary sensoria
on segments five and six. Segments three to six are very strongly imbri-
cated. Total lengths of the antennae and of the segments in m.m. are as
follows: total 1.21 to 1.39; I, .064 to .085; II, .064 in all specimens studied;
III, .234 to .255; IV, .148 to .170; V, .146 to .172; VI base, .150 to .168;
spur, .383 to .466. Rostrum dusky, rather short, scarcely reaching second
coxae. Thorax black, with well developed lobes; prothorax with very
small lateral tubercles. Wings hyaline with a greenish-yellow cast, rather
large, with normal venation in the fore wings, hind wings with but a single
cross vein; veins distinct, greenish yellow in color, stigma dusky. Length
of fore wing, 2.34 m.m. to 2.51 m.m. Legs normal, light brown in color
except the distal parts of the femora and tibiae Which are black, with
black tarsi. Abdomen rather broadly oval, very dark green in color.
Cornicles dark brown, medium in length, slightly swollen beyond the mid-
dle, with a rather marked constriction before the apex, strongly imbricated
thruout their length. Length .234 m.m. to .255 m.m. Cauda rather
broadly conical, about half as long as the cornicles; concolorous with the
abdomen, with a few short, fine, much curved hairs. Anal plate almost
triangular in shape with many fine slightly curved hairs.
Host Plant. Taken on the under side of tender leaves of
Poison Ivy (Rhus radicans L.).
Locality.-Taken near Old Man's Cave, Hocking County, Ohio,
May 31, 1924 by the author.
No apterous forms were found, the colony consisting entirely
of winged females and pupae. Described from seven alate vivi-
parous females. Color notes made from living specimens,
measurements from specimens mounted in balsam. Cotypes in
the author's collection.
This aphid is very interesting from the standpoint of its food
plant. Of the three previously described species of this Genus
one was taken on a sedge Carex sp., another on Nut Grass
(Cyperus esculentus) and the third on a moss Polytrichum com-
mune the present species is thus the first taken on one of the
higher broad-leaved plants.
FOUR UNDESCRIBED TINGITIDS FROM UNITED STATES
By CARL J. DRAKE, Ames, Iowa
Corythucha nicholi, n. sp.
Pale tastaceous, the nervures on dorsal portion of hood and tumid ele-
vations of elytra, a small spot on each paranota and median carina, two
rows of nervures near base and some nervures near apex of elytra fuscous.
Pronotum pale brown, becoming lighter on triangular portion, finely punc-
tate, tricarinate; lateral carinae strongly raised anteriorly, not extending
to the hood, each composed of three or four areolae; median carinae strong-
ly raised, a little shorter than hood and more than one half as high, com-
posed of one entire row of large areolae and a few extra areolae at its
highest part. Rostral laminae testaceous, the rostrum extending a little
beyond the middle of the mesosternum. Antennae slender, testaceous,

Huachuca Mts., Ariz., July 17, 1905, by H. G. Barber, in the col-
lections of Iowa State College, H. G. Barber, A. A. Nichol, and
the writer. This species has been confused in collection with
C. arcuata Say, but differs in having a larger and more strongly
inflated hood and the larger and more globose tumid elevations
on the elytra. In some specimens the general color is somewhat
similar to C. pallida 0. & D.
Melanorhopala balli, n. sp.

able by its much smaller size and shorter legs and antennae. Length,
3.23 mm.; width, 1.17 mm.
Antennae darker and stouter than in M. clavata Stal, the third seg-
ment slightly curved and slightly enlarged towards tip. Proportional
lengths of antennae of female-(M. ball) 1=17, II=14, II1=104, IV=13;
(M. clavata) I=30, II=16, 111=160, IV=30. Legs short, about two-thirds
as long as in M. clavata. Median spine on head greatly reduced. Discoidal
area about three-fifths as long as in M. clavata, bounded by a prominent
Holotype, brachypterous female, Fort Collins, Colorado, July
28, 1899, E. D. Ball, in author's collection. In this species the

perotingis Parshley. Pterygopolymorphisn and sexual dimor-
phism are marked characteristics of the genus Melanorhopala
Stal, especially in M. clavata Stal.
Hesperotingis floridana, n. sp.

and considerably more swollen distally. Head ferrugineous, with five
spines; median and posterior pair rather short, slender, contiguous with
the head; anterior pair short, stout, curved inwardly. Antenniferous
tubercles large, broad and prominent. Bucculae contiguous in front. Ros-
trum long, the apex concealed by "card point" behind intermediate coxae.
Antennae very stout, ferrugineous, the distal half blackish; segments I
short, slightly longer and stouter than two; III very long, strongly swollen
towards apex; IV short, subconical, distinctly narrower at its base than
the apex of the third.
Pronotum strongly swollen, shining, very coarsely pitted, ferrugineous,
the collum and margin of triangular process testaceous. Paranota nar-
row, contiguous with sides of pronotum, uniseriate. Lateral carinae
uniseriate, subparallel, a little more raised behind than in front, each
composed of single row of very small areolae; median carina also more

nervelets ferrugineous, the areolae pale; costal area uniseriate, some of
the transverse nervures thickened and darkened; subcostal area almost
entirely biseriate, with two or three extra cells opposite apex of discoidal
area; discoidal area extending beyond middle of elytra, bounded by a'prom-
inent, strongly costate, irregular nervure, narrowed at apex, with four
rows of cells at its widest part, the areolae of discoidal and sutural areas
not arranged in very regular rows. Wings a little longer than the abdo-
men. Body beneath reddish brown. Legs reddish brown, moderately
long. Length, 4.23 mm.; width 1.32 mm.
Holotype, macropterous female, East Florida, collected by
Ashmead, in U. S. National museum. This species is very dis-
tinct from any of its congeners and is probably closely allied to
H. antennata Parshley.
Hesperotingis mississippiensis, n. sp.
Brown, the antennae, lateral carinae and costate nervures separating
discordal, subcostal and sutural areas brownish black. Length, 3.19 mm.;
width, 1.13 mm.
Antennae moderately long and stout, dark brown, becoming blackish
towards apex, densely clothed with short, recurved hairs; proportional

widening posteriorly, open behind, the rostrum extend onto the first venter.
Bucculae dark brown, broad, contiguous in front, Orifice very large and
prominent. Legs dark brown. Head, spines and antenniferous tubercles
dark; anterior pair of spines stout, conical, strongly turned inwardly.
Pronotum coarsely pitted, areolate and testaceous behind; paranota
uniseriate, almost contiguous with the dorsal surface of pronotum; collum
distinct, slightly elevated in front of median carina; carinae terminating
anteriorly, at the calli, subparallel. Elytra a little longer than abdomen
brachypterouss form), rounded behind, areolae slightly confused, opaque
or subopaque; costal area uniseriate, a few of the transverse nervures
thicker and blackish, subcostal area mostly biseriate, with a few extra
areolae near apex of discoidal area; discoidal area bounded by a promi-
nent dark nerve, widest near middle, there quadriseriate, somewhat nar-
rowed at both apex and base, extending beyond middle of elytra. Wings
greatly reduced. Claspers strongly curved in male.
Holotype, brachypterous male, Charleston, Miss., Sept. 10,
1925, collected by H. M. Harris, in author's collection. This
species seems to belong to the genus Hesperotingis, the antennae
are practically straight; the elytra are formed as in brachypter-
ous form of this genus. It is most closely allied to H. duryi
Drake from Texas, but the reticulations are much more regu-
larly arranged and the antennae are quite different.
MEETINGS OF THE SOCIETY
Nov. 4-The Society met in Science Hall. Prof. Gray spoke
of his summer vacation visit to Germany and its educational
institutions. His talk was illustrated by several pictures of vari-
ous laboratories and some of the publications which the Ger-
mans use in the distribution of information among the farmers.
Dec. 2-The Society met at 4 P. M. in the rooms of the De-
partment of Entomology of the College of Agriculture. The fol-
lowing men were elected to membership: Prof. C. F. Byers of
the Department of Biology, R. A. Knight of the State Plant
Board, Mr. Ralph Dickey, Assistant in Entomology in the Col-
lege of Agriculture, Mr. Monte Moore, graduate student in Ento-
mology, College of Agriculture, Mr. Jack Creighton and R. M.

PARASITES APPRECIABLY DELAYING THE
MULTIPLICATION OF THE CITRUS APHID
The citrus aphid, Aphis spiraecola Patch, is again very scarce
this spring. At present writing its numbers are so few that
it does not seem at all probable that it can increase with suffi-
cient rapidity to do any appreciable amount of harm.
The reason for the comparative scarcity of aphis this year is
due chiefly to the character of the weather during the winter.
Because of the extreme drought of the fall and early winter,
there was very little new growth suitable for the aphids, conse-
quently very few aphids; then the freezes of January, by cut-
ting off what little new growth there was, dealt them another
very hard blow.
Mr. Thompson who is in charge of the citrus aphid work at
the Citrus Substation at Lake Alfred has observed that even
the few aphids that did go thru the winter are not increasing
in numbers as rapidly as during the same season of previous
years. His breeding cages show as many young per female
being produced as is usual during this season of the year. But
a comparison of the number of predaceous enemies of the aphids
as compared with their number a year ago shows the reason
for the slow multiplication of aphids. In connection with the
aphid work at Lake Alfred, a weekly record is kept of the pro-
portion of predators to aphids. The comparison of this year's
record with last year's shows the predators are three times as
abundant this year as they were last.
These predators are chiefly ladybeetles and the larvae of
syrphus flies. The most abundant species of ladybeetles in
aphid colonies is the Blood-red Ladybeetle which eats an aver-
age of 90 aphids per day. The young of this beetle eat from 40
to 70 per day according to age. As this ladybeetle has a gen-
eration every month, the possibilities for rapid multiplication
are great. Syrphus flies on the other hand eat aphids only in
the larval stage; but for their size they are very voracious. One
of them was found to eat 513 aphids during her larval life of ten
days. In spite, however, of the voracious appetites of these
predators and their rapid multiplication (short life history),
they are not able to stop an infestation of aphids when the con-
dition of the foliage, as in the early spring, is favorable. But
our experience this year has shown their great value in holding
down the aphids and preventing an infestation when conditions
are not especially favorable for aphids.
TWO UNDESCRIBED WATER-STRIDERS FROM GRENADA

THE FLORIDA ENTOMOLOGIST
Holotype, male; allotype, female; and morphotype, winged
female, Grenada, West Indies, Aug. 31, 1891, H. E. Summers,
collector, in collection of Iowa State College. Paratypes, taken
with type, -in collections of Iowa State College and the authors.
Notes at hand state that the specimens were taken near the
mouth of the river on brackish water, about one mile north of
St. Georges', Leeward coast. This species and T. inermis Esaki,
specimens of which are at hand from Grenada (Summers' collec-
tion), were listed by Uhler (Proc. Zool. Soc. Lond., 1894, XV, p.
213) as T. pictus Uhl. T. comitialis, n. sp. resembles T. inermis
Esaki but is slightly larger and more robust and the males lack
the longer hairs clothing the intermediate femora and tibiae.
Microvelia summers, n. sp.
Winged form: Very short, broad, robust, scarcely more than twice
as long as broad; clothed with short velvety pile; brown, a transverse spot
on front of pronotum yellowish; hemelytra pale brown, becoming paler
on basal half. Head short, broad, inserted in pronotum to eyes, the
median indented glabrous line distinct. Antennae brown, not reaching
beyond humeri of pronotum, segment I stout, slightly curved, enlarged
towards 'apex; II slenderer, thickest beyond the middle; III slenderest;
IV stout, thickest before the middle, tapering distally; the proportional
lengths of segments, I:II:III:IV-9:6:7:13. Eyes large and prominent.
Rostrum reaching'"beyond anterior coxae. Pronotum coarsely pitted,
subtruncate at the apex, the humeri prominent, the median length three-
fifths of the width thru humeri (34:55). Hemelytra slightly narrower
than abdomen, the veins not prominent. Body beneath dark. Legs short,
pale brown, the apices of tibae and tarsi lighter. Length, 1,43 mm.;
width, .61 mm.
Holotype, winged female, and allotype, winged male, Grenada, West
Indes, 1891, collected by H. E. Summers, in the Summers' collection at
Iowa State College. Paratypes, six females, taken with types, in collec-
tion of Iowa State College and the authors. The wingless form is un-
known. This unique little species is named in honor of Professor H. E.
Summers, formerly of Iowa State College, who was much interested in
aquatic Hemiptera and who made large collections in the United States
and West Indies. The very short and robust form and the antennal char-
acters serve to separate M. summers from its congeners. It is perhaps
most closely related to M. marginata Uhler, but is darker in color, and
Trepobates trepidus Drake and Harris
Proc. Biol. Soc. Wash., XLI, 1928, p. 27.
In the original description the authors erroneously state that
the rostrum extends beyond intermediate coxae, instead of an-
terior coxae. In all of the known species of the genus Trepo-,
baifes the rostrum but slightly surpasses the anterior coxae.
THE SCARABAEIDAE OF FLORIDA
By W. S. BLATCHLEY
(Continued from page 62, Vol. XI)
Genus III. CHOERIDIUM SERVILLE
This and the next five genera form the tribe Coprini dis-
tinguished by having the apical halves of middle and hind tibiae
gradually thickened, thus unfitting them for rolling balls of
dung, though some form balls which they bury on the spot. The
males usually have the head or thorax, or both, armed with a
horn or tubercle. In Choeridium the labial palpi are 3-jointed;
head and thorax unarmed; front coxae transverse, not promi-
nent. They are small, shining brown or bronzed Hister-like
10. (13057). C. histeroides (Web.).
Length 6-7 mm. Above bronzed and strongly shining; hind angles of tho-
rax more strongly rounded, their margin distinct, reflexed; punctures of
head, thorax and elytral striae very evident.

Take advantage of this two-fold control. When you
spray with "Black Leaf 40" you kill Citrus Aphid, other
Aphids, Thrips, etc., not only by direct contact (or hit-
ting) but also because of the "gassing" effects of the vola-
tile nicotine fumes. When you mix "Black Leaf 40" with
lime-sulphur, oil-emulsion, Bordeaux or calcium caseinate,
or soap, you convert nicotine sulphate into volatile nico-
tine with powerful "gassing" properties.
Likewise, when you dust with Nicotine Dust, insects are killed
by actual contact of the dust with their bodies and also by the
powerful nicotine gas.
